Explain the theory of spontaneous generation and why people once accepted it as an explanation for the existence of certain types of organisms. Explain how certain individuals (van Helmont, Redi, Needham, Spallanzani, and Pasteur) tried to prove or disprove spontaneous generation.
Francesco Redi (born Feb. 18, 1626, Arezzo, Italy—died March 1, 1697, Pisa) was an Italian physician and poet who demonstrated that the presence of maggots in putrefying meat does not result from spontaneous generation but from eggs laid on the meat by flies.

He is referred to as the "founder of experimental biology", and as the "father of modern parasitology".

Experimentation by Francesco Redi in the 17th century presented the first significant evidence refuting spontaneous generation by showing that flies must have access to meat for maggots to develop on the meat.
Spontaneous generation was taken as scientific fact for two millennia. Though challenged in the 17th and 18th centuries by the experiments of the Italian biologists Francesco Redi and Lazzaro Spallanzani, it was not discredited until the work of the French chemist Louis Pasteur and the Irish physicist John Tyndall in the mid-19th century.

May 30, 2017 · Francesco Redi was an Italian physician and the first scientist to suspect that the theory of spontaneous generation may be flawed, so he set up a simple experiment. He placed fresh meat into two different jars, one with a muslin cloth over the top, and the other left open.
